Ministers talk security in Japan

Defence Minister David Johnston and Foreign Minister Julie Bishop are in Japan for top level talks as Australia and Japan move to deepen defence and security co-operation.

The ministers were meeting their opposite numbers in Tokyo on Wednesday for the fifth Australia-Japan Foreign and Defence Ministerial (2+2) Consultations.

That follows Prime Minister Tony Abbott's visit to Japan in April where he agreed on both a trade deal and future cooperation on defence science and technology, particularly joint research on marine hydrodynamics.

In practice, that means submarines, with Australia interested in Japan's new Soryu-class boats as it looks to replacements for the Navy's six Collins submarines.

The ministers are expected to conclude negotiations on the proposed Defence Science, Technology and Materiel Agreement, announced during Mr Abbott's visit.

The agreement will allow Australia and Japan to jointly develop defence technologies, establishing a basis to deepen defence cooperation, they said.

During the visit, Ms Bishop will meet Foreign Minister Fumio Kishida and other senior Japanese ministers, parliament members and academics to discuss international and bilateral developments.

That will include the New Colombo Plan, under which students from around the region will receive scholarships to study in Australia.

Senator Johnston will meet Japanese Defence Minister Itsunori Onodera separately to discuss progress in bilateral defence engagement in areas such as logistics cooperation, exercises and training, and peacekeeping and disaster relief.

Japanese Prime Minister Shinzo Abe, who reportedly is planning to visit Australia in July, wants Japan to play a bigger role on the global stage, loosening longstanding constitutional restrictions on the role of its defence force.

He has moved to ease tight restrictions on weapons exports, paving the way for greater defence co-operation with Australia.
